Komparativní analýza akustických vlastností fetálního fonokardiografu

Abstract

This thesis deals with comparative analysis of elementary parts of fetal phonocardiograph by time-frequency analysis of fetal phonocardiographic signal (fFKG). The fetal FKG signal is affected by various aspects such as sensor movement, ambient noise, fetal movement, maternal sounds, elementary parts of a fetoscope and so on. The thesis also deals with the fetal heart and its acoustic activity, in which the heart sounds are described. Subsequently, the thesis deals with the issue of monitoring the fetal heart. The issue of monitoring is followed by a research section, which describes the history and new possibilities of sensing fFKG signal. Based on the research part, elementary parts of fetal phonocardiograph are tested, analyzed and subsequently evaluated. Based on these results, the most ideal composition of fetal phonocardiography is designed and tested on a pregnant woman at 34th weeks of pregnancy.
